As per title, been using this for more than 10 years in my house, old house layout where the switch for heater is in my room
Recently it burnt, so it concerned me as is it ok to use 13a for this water heater, or it's best to change to the 20a on off switch, or the 15a round plug and socket? Thanks!
Your water heater is rated at 15A while your plug is 13A, obviously it overloads it.Recently it burnt, so it concerned me as is it ok to use 13a for this water heater, or it's best to change to the 20a on off switch, or the 15a round plug and socket? Thanks!
If follow ST guidelines, it has to be directly connected or using a proper certified connector and 4 sqmm cable.
In practice 2.5 sqmm cable works fine if your water heater does not exceed 20A.
Just take note newer water heaters today may consume beyond 15A, hence, even using 15A plug/socket (The round pins) is not advisable.
